[0016] like Figures 1 to 5 As shown, the feeding mechanism for preparing tableware materials proposed in this embodiment includes: The feeding cylinder 1 is inclined, with an opening on its left side and a U-shaped seat fixedly connected thereto. A central shaft is rotatably mounted on the inner wall of the right side of the feeding cylinder 1. A spiral conveying blade 101, which is movably sleeved inside the feeding cylinder 1, is fixedly connected to the outer side of the central shaft.

A through hole is opened on the right side of the U-shaped seat, and bearings are fixedly mounted in the through hole and on the inner wall of the right side of the feeding cylinder 1. The inner ring of the bearing is fixedly fitted to the outer side of the central shaft, which serves to rotate the central shaft. The conveying motor 103 is used to drive the central shaft and the spiral conveying blade 101 to rotate. The rotation of the spiral conveying blade 101 is used to convey the tableware material added through the feeding hopper to the upper right. The tableware material conveyed to the upper right is gradually discharged downward through the discharge pipe 102. L-shaped support plate 2 is fixedly connected to the bottom of the conveying cylinder 1; The vertical guide lifting drive assembly is installed on the L-shaped support plate 2; the vertical guide lifting drive assembly is used to drive the feeding cylinder 1 to move up and down so as to flexibly adjust according to the height of the feeding port at the top of the tableware preparation equipment. The quantitative weighing and feeding assembly is fixedly connected to the bottom right side of the feeding cylinder 1; The PLC controller 3 is fixedly connected to the bottom inner wall of the L-shaped support plate 2 and is electrically connected to the conveyor motor 103 and the quantitative weighing and feeding assembly through wires. The quantitative weighing and feeding assembly is used to weigh and quantitatively feed the discharged material under the control of the PLC controller 3. When the weighed weight reaches the preset value, the PLC controller 3 controls the conveyor motor 103 to shut down and automatically stop the conveying work, so as to realize the quantitative feeding work into the feed port of the tableware preparation equipment.

[0017] Furthermore, such as Figure 1 and 2As shown, the vertical guide lifting drive assembly includes a base plate 201, an electric telescopic rod 202, and four first T-shaped guide rods 203.

The four first T-shaped guide rods 203 are fixedly connected to the top of the base plate 201 in a rectangular shape. The L-shaped support plate 2 is slidably sleeved on the four first T-shaped guide rods 203. The material conveying cylinder 1 is located between the two first T-shaped guide rods 203 on the front side and the two first T-shaped guide rods 203 on the rear side. In this embodiment, a counterweight box is fixedly installed on the top left side of the base plate 201. The four corners of the top of the base plate 201 are provided with mounting holes. The counterweight box is used for personnel to add counterweights such as stones to the left side of the base plate 201 to improve the stability of the device when it is placed. The bottom inner wall of the L-shaped support plate 2 is provided with four vertical guide holes that slide and fit with the outer side of the corresponding first T-shaped guide rod 203, which serve to guide the vertical sliding of the L-shaped support plate 2. In this embodiment, the base plate 201, the electric telescopic rod 202, and the four first T-shaped guide rods 203 work together. The electric telescopic rod 202 drives the L-shaped support plate 2 to slide upward or move downward on the four first T-shaped guide rods 203. The L-shaped support plate 2 drives the feeding cylinder 1 to move upward or move downward to adjust its height. This achieves the effect of flexibly adjusting the feeding height according to the height of the feeding port at the top of the tableware preparation equipment, thereby improving applicability.

[0018] Furthermore, such as Figure 2 , 3As shown in Figures 4 and 5, the quantitative weighing and feeding assembly includes an L-shaped support 4, four second T-shaped guide rods 401, a weighing sensor 402, a receiving box 403, a rectangular feeding tube 404, a push plate 407, an L-shaped sealing plate 405, two horizontal guide rods 406, and a reciprocating electric push rod 408. The L-shaped support 4 is fixedly installed on the bottom right side of the feeding cylinder 1. The weighing sensor 402 is fixedly installed on the bottom inner wall of the L-shaped support 4. The receiving box 403 is fixedly installed on the top of the weighing sensor 402. The four second T-shaped guide rods 401 are rectangularly and fixedly connected to the bottom of the receiving box 403. The L-shaped support 4 is slidably sleeved on the outside of the four second T-shaped guide rods 401. The rectangular feeding tube 404... The connecting rod is fixed to the bottom right side of the receiving box 403; the reciprocating electric push rod 408 is fixedly installed on the left side of the receiving box 403; the push plate 407 is in movable contact with the inner wall of the left side of the receiving box 403 and is fixedly connected to the extended end of the reciprocating electric push rod 408; the two horizontal guide rods 406 are fixedly connected to the right side of the push plate 407; the right ends of the two horizontal guide rods 406 slide out to the outside of the receiving box 403 and are fixedly connected to the inner wall of the right side of the L-shaped sealing plate 405; a sealing gasket that is in movable contact with the bottom end of the rectangular feed tube 404 is glued and fixed on the bottom inner wall of the L-shaped sealing plate 405; the weighing sensor 402 and the reciprocating electric push rod 408 are both electrically connected to the PLC controller 3 through wires. In this embodiment, the bottom of the L-shaped support 4 has four rectangular guide holes that slide and fit with the outer side of the corresponding second T-shaped guide rod 401, allowing the second T-shaped guide rod 401 to pass through and be vertically guided. The discharge pipe 102 is located above the middle of the two horizontal guide rods 406. A rectangular through hole is opened on the left inner wall of the L-shaped support 4, and the reciprocating electric push rod 408 is located in the rectangular through hole and does not contact the inner wall of the rectangular through hole, thus avoiding the reciprocating electric push rod 408. The receiving box 403 has two horizontal guide holes on the right inner wall that slide and fit with the outer side of the corresponding horizontal guide rod 406, allowing the horizontal guide rod 406 to pass through and be horizontally guided. In this implementation scheme, the L-shaped support 4, four second T-shaped guide rods 401, a weighing sensor 402, a receiving box 403, a rectangular feeding pipe 404, a push plate 407, an L-shaped sealing plate 405, two horizontal guide rods 406, and a reciprocating electric push rod 408 work together. Based on the required amount of tableware material added each time, the PLC controller 3 pre-sets the weight value for controlling the shut-off of the conveyor motor 103 and the forward start of the reciprocating electric push rod 408. It also pre-sets that the reciprocating electric push rod 408 will reverse and reset fifteen seconds after forward start. This weight value is specifically the sum of the weight of the top structure detected by the weighing sensor 402 and the required amount of material to be added. When the conveyor motor 103 drives the spiral conveyor blade 101 to rotate via the central shaft, conveying the added tableware material to the upper right, the tableware material is gradually discharged slowly downwards through the discharge pipe 102 into the receiving box 403. The weighing sensor 402 detects the total weight of the receiving box, its structure, and the tableware material, and converts this into a standard electrical signal, which is then transmitted via a soft... The signal is transmitted to the PLC controller 3 via a wire. The PLC controller 3 converts the received standard electrical signal into an actual weight value through analog-to-digital conversion. When the preset pressure value is reached, the PLC controller 3 controls the conveyor motor 103 to shut down, stopping the conveying operation. It also controls the reciprocating electric push rod 408 to start forward, driving the push plate 407 to move to the right. The push plate 407, through two horizontal guide rods 406, drives the L-shaped sealing plate 405 to move to the right, unsealing the bottom end of the rectangular feeding tube 404. The rightward-moving push plate 407 then pushes the tableware material to the right. Push it to the rectangular discharge tube 404, so that it is discharged downward through the rectangular discharge tube 404 into the feed inlet of the tableware preparation equipment. After fifteen seconds, the PLC controller 3 controls the reciprocating electric push rod 408 to start in reverse to reset, so as to drive the push plate 407 and the L-shaped sealing plate 405 to move back to the left to reset, and seal the bottom end of the rectangular discharge tube 404 again. Then it can wait for the weighing and quantitative feeding to be carried out again, so as to achieve the effect of quantitative feeding into the feed inlet of the tableware preparation equipment, improving the accuracy and convenience of feeding.

[0019] It should be noted that the PLC controller 3 preferably adopts a Siemens S7-200SMART programmable controller with an integrated analog input module, which can receive the standard electrical signal output by the load cell 402 and convert it into the actual weight value through the integrated analog-to-digital converter; the load cell 402 preferably adopts a Transcell BSS series plate (pressure) load cell; the conveyor motor 103, the reciprocating electric push rod 408 and the load cell 402 are all electrically connected to the PLC controller 3 through flexible wires. The technology of establishing an electrical connection controlled by the PLC controller 3 by direct connection of flexible wires is a conventional and well-known method of conventional wire control in existing controllers, and will not be described in detail here; Regarding power supply: Since this device is used in the production and processing of tableware materials, there is no shortage of power supply measures at the production and processing site. All electrical components of this device are connected to the mains power on site and are connected to the power input interface of each device through conventional power distribution devices such as circuit breakers, contactors, and power modules (not marked in the figure) to form a complete power supply circuit. This power supply scheme is a conventional power distribution method for industrial equipment, and all are conventional, mature and well-known methods, so it will not be described in detail here.

[0020] The usage method of this embodiment is as follows: When using the feeding mechanism for tableware material preparation, the electric telescopic rod 202 drives the L-shaped support plate 2 to slide upward or move downward on the four first T-shaped guide rods 203. The L-shaped support plate 2 drives the feeding cylinder 1 to move upward or move downward to adjust its height. After adjustment, the device is placed on one side of the tableware material preparation equipment, and the rectangular feeding pipe 404 is located above the feeding port of the tableware material preparation equipment. By adjusting the height of the feeding cylinder 1, the feeding height can be flexibly adjusted according to the feeding port height at the top of the tableware preparation equipment, which is convenient to adapt to tableware material preparation equipment with various feeding port heights and improves applicability. Based on the required amount of tableware material to be added each time, the PLC controller 3 pre-sets the weight value for controlling the shut-off of the conveyor motor 103 and the forward start of the reciprocating electric push rod 408. It also pre-sets that the reciprocating electric push rod 408 will reverse and reset fifteen seconds after forward start. This weight value is specifically the sum of the weight of the top structure detected by the weighing sensor 402 and the required amount of material to be added. When the conveyor motor 103 is started, driving the spiral conveyor blade 101 to rotate via the central shaft and convey the added tableware material to the upper right, the tableware material is gradually discharged slowly downwards through the discharge pipe 102 into the receiving box 403. The weighing sensor 402 detects the total weight of the receiving box, its structure, and the tableware material, and converts it into a standard electrical signal, which is transmitted to the PLC controller 3 via a flexible wire. The PLC controller 3 converts the received standard electrical signal into an actual weight value through analog-to-digital conversion. When the preset pressure value is reached... PLC controller 3 controls the conveyor motor 103 to shut down, stopping the conveying operation, and controls the reciprocating electric push rod 408 to start forward, driving the push plate 407 to move to the right. The push plate 407 drives the L-shaped sealing plate 405 to move to the right through the two horizontal guide rods 406, unsealing the bottom end of the rectangular feeding tube 404. The right-moving push plate 407 pushes the tableware material to the right to the rectangular feeding tube 404, allowing it to be discharged downwards into the tableware preparation equipment inlet. After fifteen seconds, PLC controller 3 controls the reciprocating electric push rod 408 to start in reverse to reset, driving the push plate 407 and L-shaped sealing plate 405 to move back to the left to reset, sealing the bottom end of the rectangular feeding tube 404 again. Then, it can wait for the weighing and quantitative feeding operation to start again, realizing the effect of automatic quantitative feeding into the tableware preparation equipment inlet. It can automatically and accurately control the amount of material by weighing, improving the accuracy and convenience of feeding.

[0021] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
